The study of using refrigerator effluent as an energy source and fertilizer generation is justified due to the main problem with a refrigerator: the generation of waste. The purpose of the work was to seek an alternative for the use of the refrigerator effluent (Red line, Green line). The calorific value was quantified in order to determine the capacity to feed an energy generator and to evaluate whether the burning residue is viable for soil fertilization. For this, 3 pyrolysis processes were carried out at different temperatures, obtaining the biochar. In addition, thermal analyzes, X-ray diffraction analyzes, and X-ray fluorescence spectrometry analyzes were conducted. The results of the analyzes showed that the values of calorific value obtained were close to those of other materials already proven in the literature. Thus, it is concluded that biocarbons from the refrigerator have favorable properties for the energy generation process.The samples showed a large amount of Carbon and other elements such as Silicon, Calcium, Phosphorus and Potassium in their composition, indicating that biochar deserves to be better studied as a possible fertilizer.
